How to organise a congress in Barcelona: 24-month timeline and checklist

Organising a congress in Barcelona is a two-year project with many interdependent parts: if the venue is not secured, you cannot block hotels; if the scientific programme slips, so do accreditation and sponsorship. This guide puts those parts in order over time and explains what to decide at each stage. It is written from our experience as congress organisers in Barcelona, with a team that has more than 20 years' experience organising events.

Why choose Barcelona for your congress?

Barcelona is one of the most active association congress destinations in the world. In the 2025 ICCA ranking it was the third city in the world by number of international association meetings, according to the Catalunya Convention Bureau. In 2025 Turisme de Barcelona recorded a total of 597 association meetings (congresses, one-day meetings and courses) with 401,315 delegates.

A useful figure for planning: only 30.3% of association meetings in 2025 were held in hotels, compared with 92.4% of corporate meetings. Congresses are spread across convention centres, exhibition venues, hospitals, universities and unique venues, which is why the choice of venue matters more than for a company convention. You will find the full destination data on our MICE Barcelona page.

Who does what at a congress?

Before opening the timeline, it is worth being clear about roles. The most common confusion is the scientific committee taking on logistical tasks or the PCO deciding on content.

If you want the detail of each role, we explain it in PCO, DMC and event agency: the differences.

The 24-month timeline

This is the overview we use for a medium-sized or large international congress. Each row is a workstream; each dot shows when it is active. For national congresses, compress the first three columns into one.

Milestones that must not move

1. M-24 to M-18. Decision to bid, preferred and alternative dates, first budget with attendance scenarios, shortlist of two or three venues.
2. M-18 to M-12. Venue contract signed, first hotel room blocks, scientific committee set up, draft sponsorship prospectus.
3. M-12 to M-9. Congress website live, call for abstracts opens, early-bird registration opens, first sponsors confirmed.
4. M-9 to M-6. Abstract submission closes, committee review, preliminary programme, exhibition floor plan largely sold.
5. M-6 to M-3. Acceptance notifications, final programme, accreditation application, first room release date, AV and catering contracted.
6. M-3 to M-1. Early-bird registration closes, accommodation lists, running order for each room, exhibitor manual, supplier dress rehearsal.
7. Congress week. Set-up, on-site congress secretariat, speaker ready room, badges, capacity control and social programme.
8. After. Certificates, survey, final accounts with the venue and hotels, report for the committee and for the next edition.

The bid: how convention bureaus help you

Many international congresses rotate between cities and the association chooses its destination through a bidding process. In Barcelona you can rely on two public bodies, and their help is free.

Barcelona Convention Bureau (BCB), a Turisme de Barcelona programme. According to its own website it offers:

• Advice on venues, accommodation and suppliers.
• Coordination of site inspections.
• Liaison with city bodies and institutions for municipal services and protocol.
• Logistical and financial support for bids: planning the process, preparing the dossier, images and audiovisual material, taking part in the presentation, coordination with local authorities and promotion of the congress once it has been won.
• Free listing of the event and tourist material for participants.

Catalunya Convention Bureau (CCB), a programme of the Agència Catalana de Turisme. It offers free, tailored advice, fam trips, support in preparing the bid presentation, contact with specialist companies and organisations, and documentation for delegates. It also runs an ambassador programme with professionals from the region who champion congresses in their field.

How we prepare a bid

1. Read the association's request for proposals. Venue requirements, number of breakout rooms, exhibition space, maximum hotel rate, accessibility and sustainability criteria.
2. Check dates against the city calendar. A bid that clashes with a major trade fair loses points on price and hotel availability. See our Barcelona trade fair calendar 2027.
3. Provisional venue and hotel agreements. Options with an expiry date aligned with the association's decision.
4. Bid budget with low, medium and high attendance scenarios, so the association can see the break-even point.
5. Dossier and presentation, with support from the BCB or the CCB, and a site inspection for the evaluation committee.

How to choose the venue

The rule of thumb is to size the venue to the programme, not just to the total number of delegates. A congress of 1,500 people with eight parallel sessions and a commercial exhibition needs more space than a convention of 2,000 people in plenary.

The exact capacities by room and format are on each venue page and in our convention centres comparison. If you are looking for a space with more character for small sessions or institutional events, see our unique venues.

What we always ask the venue

• Set-up and breakdown times and the cost of overnight overtime.
• Exclusive or open catering. Many venues work with in-house or approved caterers, and that shapes the price of breaks and meals.
• AV and connectivity. Whether the technical supplier is in-house, whether you can bring your own and what a dedicated line costs.
• Delegate flow. The distance between plenary, breakout rooms, exhibition and coffee area. A commercial exhibition works when the coffee is inside it.
• Safety rules and capacities by room, and the evacuation plan.
• Cancellation and force majeure terms, with the payment schedule.

Scientific committee, programme and call for abstracts

The programme is the reason people travel. The PCO does not decide it, but it does give it a structure so that it arrives on time.

The abstracts timeline we propose:

Recommendations that prevent problems:

• A single platform for submission, review, programme and mobile app. Copying data between systems creates errors in names and affiliations.
• Written review criteria and a fixed number of reviewers per abstract.
• Registration linked to acceptance. If the author does not register in time, their submission is removed from the programme.
• A speaker ready room with a technician, to receive and test presentations the day before each session.

Registration and congress secretariat

The congress secretariat is the point of contact for every delegate. In practice it handles:

• Fee types: early-bird, standard and on-site; member and non-member; resident or student; one-day fee; accompanying person where the congress policy allows.
• A clear cancellation and name-change policy from day one.
• Invoicing to delegates, companies and sponsors registering groups.
• Invitation letters for delegates who need a visa, with enough time for the consular appointment.
• Data protection, with consent to share data with sponsors only when the delegate agrees.
• On-site registration with self-service badge printing and a help desk.

It is best for the early-bird fee to close after abstract notification: many authors wait to know whether their work has been accepted before registering.

Sponsorship and commercial exhibition

At many medical and scientific congresses, sponsorship covers a significant part of the budget. This is how we approach it:

1. Sponsorship prospectus with tiered packages, standalone opportunities (satellite symposium, coffee break, app, lanyards) and the exhibition floor plan.
2. A commercial floor plan that guarantees traffic to every stand: coffee, posters and lunch inside the exhibition.
3. Exhibitor manual with set-up times, venue rules, floor loads, electricity and official suppliers.
4. Compliance review before selling: what the sponsor's industry code allows and whether the congress needs prior assessment.

Medical education accreditation: EACCME

If your congress is aimed at doctors and you want to offer European credits, the usual route is EACCME accreditation from the UEMS (European Union of Medical Specialists). EACCME recommends submitting the accreditation application for a live event at least 8 weeks before it starts. Late applications pay a surcharge and there is a deadline after which they are not accepted.

What usually delays the application:

• A scientific programme without fixed times or with speakers still to be confirmed.
• Missing conflict of interest declarations from speakers and the committee.
• Questions about the role of sponsors in the content.

That is why accreditation sits in the M-6 to M-3 window in the timeline: the programme has to be finalised before you apply.

Compliance: medical congresses with industry support in Spain

If pharmaceutical companies or medical technology companies take part in your congress, their code of ethics shapes the design of the event. It is not a formality to be dealt with at the end.

Farmaindustria Code of Good Practice (2025 edition)

The points most relevant to organisation:

• Meals: a maximum of €70 per guest, taxes included, at meetings held in Spain. Outside Spain, the limit of the host country's national association applies.
• Scientific content: it must take up most of the time, with a minimum of 60% of each day (the supplementary rules take 8 hours as the reference day and do not count travel time).
• Entertainment: companies may not organise or contribute to meetings with leisure or entertainment activities.
• Accompanying persons: hospitality does not extend to people who are not healthcare professionals, and companies should not allow accompanying persons at meetings they organise.
• Venue: purely tourist locations must be avoided and the venue chosen should project an appropriate image.
• Prior notification: meetings organised or sponsored by companies must be notified to the Unidad de Supervisión Deontológica (Ethics Supervision Unit) before they take place. According to the system's own official answers, notification is mandatory when the meeting includes at least one overnight stay and at least 20 healthcare professionals practising in Spain take part.

Farmaindustria's Self-Regulation System also publishes guidance to help companies decide whether to take part in third-party congresses. It includes making congress information public at least one month ahead for national congresses and two months ahead for international ones, and criteria on five-star hotels when fewer than 200 healthcare professionals attend.

Medical technology: Conference Vetting System

MedTech Europe member companies may only support a third-party educational event (with grants, stands, advertising or satellite symposia) if the Conference Vetting System has assessed it positively. The system looks at six criteria: scientific programme, geographical location, venue, hospitality, registration package and communication. If you expect sponsorship from this sector, submit the congress for assessment as soon as you have a preliminary programme and a venue.

This section summarises public rules and does not replace review by each sponsor's compliance department.

Accommodation: room blocks, releases and trade fair weeks

Accommodation is where most money is lost if it is handled late or with too much optimism.

• Block rooms in several hotels and categories near the venue or with good metro links. A single large hotel concentrates the risk.
• Negotiate staggered releases (for example at 90, 60 and 30 days) rather than a single cut-off date.
• Review the attrition clause for unused rooms and how it is calculated. Ask for rooms resold by the hotel to count in your favour.
• Watch the trade fair calendar. In 2027, ISE takes place from 2 to 5 February and MWC from 1 to 4 March at Fira Barcelona Gran Via. These are weeks of maximum hotel pressure.
• Include the tourist tax in the delegate package calculation. We explain it in our tourist tax guide for groups.

To choose hotels, see our selection of convention hotels and our guide to the best convention hotels.

Social programme

The social programme improves the delegate experience and, often, attendance at the next edition. The classic format is:

• Welcome reception the evening before or on the first day, at the venue itself or a nearby space.
• Official congress dinner at a venue with a distinctly Barcelona identity.
• Optional activities for delegates and, where the congress allows, for accompanying persons.

For Establishment Labs' WSEI congress we organised two gala dinners, one at Llotja de Mar and a farewell dinner at the Drassanes Reials. We tell the story in the WSEI congress case study. If you are looking for a venue for the official dinner, you will find options by capacity in our gala dinners for large groups guide.

Remember that at meetings supported by the pharmaceutical industry, the gala dinner must be reasonable and moderate and cannot include added cultural, leisure or entertainment elements.

Congress week

A well-prepared congress week looks very much like the running order that was written a month earlier. What you cannot do without:

• Set-up with a floor plan signed off by the venue, the relevant emergency services and the technical supplier.
• A stage manager in each room with the session running order and a direct line to technical control.
• A speaker ready room open from the day before.
• An on-site congress secretariat with multilingual staff.
• Access control to rooms with limited capacity and badge scanning if credits are awarded.
• A daily coordination meeting first thing with the venue, catering, technical team and committee.
• An incident plan: a speaker who does not arrive, a connection failure, a full room, a schedule change.

After the congress

• Certificates of attendance and credits, where applicable.
• Survey of delegates, speakers and exhibitors.
• Room reconciliation with each hotel and review of penalties.
• Final accounts and close-out with the venue.
• Final report for the committee with figures, lessons learned and recommendations for the next edition.

How we handle congresses at ECB

We are a single team from start to finish: we plan the timeline, negotiate with venues and hotels, set up the congress secretariat and produce the congress and its social programme. We can also take on just one part, such as the venue and accommodation or the technical production. If the congress needs destination services (transfers, activities, excursions), we cover them as a DMC in Barcelona. You can see examples in our case studies.

If you are considering Barcelona for your next congress, tell us about the project: we will send you a first proposal with venues, timeline and estimate within 24 business hours.
